This repo contains a comprehensive list of smart contract auditor tools and techniques that can be utilized by both smart contract auditors and blockchain developers for developing secure smart contracts

Ethereum Commonwealth Security Department conducted over 400 security audits since 2018. Not even a single contract that we audited was hacked. You can access our audit reports in the ISSUES of this repo. We are accepting new audit requests.

Security issues in Ethereum demonstrated in mocha tests. The fix is also demonstrated
